  • Acoustic source separation
    Patent number: 9473841
    Abstract: A system for directionally selective sound reception comprises an array of pressure sensors each arranged to output a pressure signal indicative of pressure, and processing means arranged to receive the pressure signals, identify a plurality of frequency components of the signals, identify at least one source direction, and identify at least one of the components as coming from the source direction. The sensor array comprises support means having two opposite sides and four sensors, at least one of the sensors being supported on each of the sides of the support means.
    Type: Grant
    Filed: March 26, 2013
    Date of Patent: October 18, 2016
    Assignee: University of Surrey
    Inventors: David Nugent, Banu Gunel
  • Acoustic source separation
    Patent number: 9093078
    Abstract: A method of separating a mixture of acoustic signals from a plurality of sources comprises: providing pressure signals indicative of time-varying acoustic pressure in the mixture; defining a series of time windows; and for each time window: a) providing from the pressure signals a series of sample values of measured directional pressure gradient; b) identifying different frequency components of the pressure signals c) for each frequency component defining an associated direction; and d) from the frequency components and their associated directions generating a separated signal for one of the sources.
